Arsenal want to sign Ajax defender Lisandro Martinez to provide cover at centre-back and left-back, according to reports.
The Argentina international, 24, is a central defender by trade and is capable of filling in on the left or in midfield when needed. Manchester United are also believed to be interested in signing Martinez but new manager Erik ten Hag doesn't see him as a left-back.
Ten Hag usually deployed Martinez at centre-back when he was manager of Ajax, leaving his position after four-and-a-half years last month to take the United job. The Newell's Old Boys academy graduate is Ajax's reigning Player of the Year, a measure of what he can offer to Arsenal or United.
